Effects of deuteration on the structure and magnetic properties of bis-quinolinium tetrabromidocuprate(II) dihydrate

The partially [d(6), 2] and fully [d(20), 3] deuterated analogues of (QuinH)(2)CuBr4 center dot 2H(2)O (d(0), 1) were prepared and their crystal structures were determined [Quin = quinoline]. In both compounds, there is a clear disorder in the positions of the bromide ions which was resolved. This led to a reexamination of the structure of the parent, fully protonated compound (1) where a small percentage of previously unrecognized disorder was also observed and the structure rerefined. Variable temperature magnetization measurements over the range 1.8-310 K indicate that all three materials behave as magnetically well-isolated layers that can be evaluated using the 2D-quantum Heisenberg antiferromagnetic model. Final fitting results for the partially (J = -5.96(5) K) and fully (J = -5.77(2) K) deuterated compounds indicate slightly weaker exchange compared to the protonated compound (J = -6.17(3) K), likely as a result of the increased disorder in the deuterated phases.

Regenerated keratin-encapsulated gold nanorods for chemo-photothermal synergistic therapy

Gold nanorods (AuNRs) have been widely applied to photothermal therapy against cancer. However, the chemically synthesized AuNRs such as that via seed-mediate method usually demonstrated a high cytotoxicity due to the existence of cetyltrimethylammonium bromide (CTAB) coating. In this work, keratin, a family of cysteinerich structural fibrous proteins was used for the first time to encapsulate AuNRs by a simple mixing method. Compared with CTAB-AuNRs, the keratin-encapsulated AuNRs (AuNRs@Kr) showed an improved colloid stability and good biocompatibility including low cytotoxicity and hemolytic effect. Moreover, AuNRs@Kr exhibited great potential as drug carriers with redox-responsive drug release behavior, due to the high concentration of disulfide crosslinking in keratin coating, and the DOX-loaded AuNRs@Kr demonstrated higher chemo-photothermal synergistic therapy efficiency against 4T1 cells compared with either free DOX or AuNRs@ Kr alone, suggesting a promising nanoplatform for cancer therapy.

Gemini surfactant/polymer/silica stabilized oil-in-water nanoemulsions: Design and physicochemical characterization for enhanced oil recovery

The present study deals with the synthesis and characterization of oil-in-water nanoemulsion systems for application in enhanced oil recovery (EOR). Nanoemulsions stabilized by N,N’-bis((dimethyltetradecyl)-1,6-hexanediammonium bromide) gemini surfactant (14-6-14 GS), partially hydrolyzed poly-acrylamide (PHPA) polymer and/or silica (SiO2) nanoparticle were synthesized by ultrasonication technique. Nanoparticles strengthen the mechanical barrier (electrostatic repulsion + steric hindrance) at oil-aqueous interfaces, resulting in increased ionic strength and droplet stability. Dynamic light scattering (DLS) results confirmed the formation of nano-sized (< 500 nm) oil droplets within bulk emulsion phase. Kinetic stabilities of nanoemulsions were investigated by zeta potential and phase behavior analyses. Surface tension of surfactant-stabilized nanoemulsions increased with PHPA addition. However, silica particles improved adsorption ability of surfactant-polymer-nanoparticle (SPN) systems, causing decrease in surface tension. Rheological experiments were conducted as screening experiment at different temperatures to identify pseudoplastic character, and flow parameters were fitted using the Power law model. Contact angle studies showed that nanoemulsions alter the wetting characteristics of rock from intermediate-wet to favorable water-wet condition. Core-flooding studies revealed tertiary oil recovery percentage of 26.25% of original oil in place (OOIP) by chemical injections of {14-6-14 GS + PHPA + SiO2} nanoemulsions, after conventional water-flooding. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2623-87-2 help many people in the next few years.

Analysis of critical parameters of flow and solute transport in porous media

Groundwater has immense importance when it comes to sustaining agricultural and domestic water demand. However, improper use of groundwater has led to drastic increase in its contamination. For efficient management of groundwater it is important to have a thorough understanding of parameters that influence the groundwater flow and solute transport. In this study, HYDRUS-1D/2D software is used to analyse the effect of critical parameters that influence the behaviour of solute in groundwater flow and its transport under different soil conditions. Also, single porosity and dual porosity approaches are discussed with their respective sensitive parameters. Parameter variations are illustrated in the forms of concentration contours of the solute spread and the breakthrough curves obtained over the flow period. The results of this work can be useful in analysing flow and solute behaviour in the vadose zone.

Regioselective N-alkylation of 2-(3,4-dimethoxyphenyl)imidazo[4,5-b] and [4,5-c]pyridine oxide derivatives : Synthesis and structure elucidation by NMR

Imidazopyridines can exist in several tautomeric forms such as benzimidazole or purine condensed systems. Regioselectivities were determined for N-alkylations of 2-(3,4-dimethoxyphenyl)- imidazopyridines and their 4 and 5-oxides (2-4, 13, 14) with n-butyl and 4-fluorobenzyl bromides under basic conditions (K2CO3 in DMF). It was observed that N-4 (5-8) and N-5 (15-17) regioisomers were mainly formed. Compounds 7 (N-4) and 7a (N-1) were separated from the mixtures of regioisomers in a 50 : 1 ratio. Their structural assignments were made with the use of two-dimensional H-1-H-1 NOE (nuclear overhauser effect spectroscopy [NOESY]) enhancements between the N-CH2 and protons on the C-4, 5, 6, and 7 positions of the pyridine moiety. To verify the NOESY data, synthesis of compounds 7a and 7b was achieved by the selective method. Complementary structural information was provided by 2D-HMBC spectra of the compounds.

Highly active and stable Ni-incorporated spherical silica catalysts for CO(2)methanation

Nickel-doped spherical silica (SSP) catalysts with ca. 10 wt% Ni were prepared via a sol-gel method using cetyltrimethyl ammonium bromide as the structure directing agent with different loading sequences of Ni and Si sources (Si1_Ni2, Ni1_Si2, and Ni_Alt_Si). For comparison purposes, the SSP supported Ni catalysts were also prepared by impregnation method (Ni/SSP (Imp)). All the prepared catalysts showed spherical shape with high specific surface area (357-868m(2)/g). The X-ray diffraction and H-2-temperature programmed reduction results revealed the stronger interaction between Ni and SiO2 in the form of nickel silicate for all the Ni-doped SSP catalysts except Ni/SSP (imp), in which only NiO species were detected. For the reaction temperature 350 degrees C, the CO2 conversion was in the order: Ni_Alt_Si (51%) > Ni1_Si2 (49%) > Si1_Ni2 (28%) > Ni/SSP (Imp) (10%) with methane selectivity 80-95%. The superior performances of the Ni_Alt_Si catalyst were correlated well to the higher electron density of Ni on the surface and higher CO2 adsorption ability as revealed by the X-ray photoelectron spectroscopy and CO2-temperature program desorption results.

Anticancer and apoptotic activity of biologically synthesized zinc oxide nanoparticles against human colon cancer HCT-116 cell line- in vitro study

Aim of this study was to synthesize the safe and stable zinc oxide nanoparticles (ZnONPs) from the leaves of Artocarpus heterophyllus. The alter in the color of the leaf extract dark brown upon addition of zinc nitrate Zn(NO3) confirms the formation of Zinc Oxide nanoparticles (ZnONPs). UV-VIS spectrophotometric analysis showed lambda max at 235 nm while Fourier transform infra-red (FTIR) spectroscopy showed various amines and amides are involved in the stabilization of ZnONPs. Energy dispersive X -rays (EDX) confirms the presence of zinc. Transmission electron microscopy (TEM) analysis revealed particle size ranges from 12 to 24 nm. These observed characteristic of nanoparticles are extremely useful in anticancer activities against HCT-116 colon cancer cell line. These ZnONPs showed IC50 value at 20 mu g/ml while on normal Vero cell line showed less effective by MTT assay. Furthermore, these nanoparticles were evaluated for apoptotic activity by acridine orange/ethidium bromide (AO/EB) double staining method showed the membrane blebbing and chromatin condensation.

Hydroformylation of natural olefins with the [Rh(COD)(mu-OMe)](2)/TPPTS complex in BMI-B(F)4/toluene biphasic medium: Observations on the interfacial role of CTAB in reactive systems

The complex [Rh(COD)(mu-OMe)](2) in presence of TPPTS (TPPTS = triphenylphosphinetrisulfonate) was evaluated as catalyst precursor for the in situ hydroformylation of natural olefins (eugenol, estragole and safrole) in biphasic media BMIm-BF4/toluene. Under moderate reaction conditions, the substrates showed the following reactivity order: eugenol > estragole > safrole. The rhodium system showed a high activity and selectivity towards the desired aldehydes. It was found that the use of cetyltrimethylammoniun bromide (CTAB) as phase transfer agent inhibits the hydroformylation reaction. The catalytic phase can be recycled up to four times without evident loss of activity or selectivity. In this work we report the use of an ionic liquid with hydrophilic character, without using water in the reaction medium.
